Display Time-likes with more precision

Specifically, include subseconds in the inspected version of the
time-like to match the absolute maximum precision you can use when
defining a Time. This means that the following two Times will no longer
appear as though they are the same time when diffed:

    Time.at(1620017167711.0 / 1000)
    Time.local(2021, 5, 2, 22, 46, 7, 710_999)
